5 Beauty Must-Haves For The Beach by 5 Beauty Must-Haves For The BeachSwimsuit? Check! Sunglasses? Check! Chick-lit? Check! You're almost ready to hit the beach, but don't forget to stock your bag with these key products for pretty skin and hair. Waterproof eyeliner We'd rather look more au naturel Aniston than va-va-voom Kardashian at the beach, but that doesn't mean we can't employ a few smart tricks to help get us there. Waterproof liner along the top lashes helps to define eyes sans mascara. Try a soft brown like Yves Saint Laurent Waterproof Eyeliner in Patent Leather. SPF Going to the beach without sunscreen is like riding a motorcycle without a helmet (aka not a wise thing to do) "Use a cream formula, since sprays can get picked up by the wind during application, reducing the amount of sunscreen that's actually applied to the skin," says Anne Chapas, M.D., assistant clinical professor of dermatology at New York University School of Medicine. "One of my favorites is La Roche-Posay Anthelios 40 Sunscreen because it helps guard against UVA damage, thanks to the ingredient Mexoryl."Strand savior: Both saltwater and chlorine dry hair out, says Greg Ruggeri, owner of Salon Ruggeri in New York City. Before you hit the beach, coat locks with a leave-in conditioner like L'Oreal Paris Vive Pro Glossy Style Conditioning Spray, which protects against sun- and saltwater-induced dullness. Personal shade maker: Besides looking super-chic, a large brimmed hat keeps the sun (and wrinkles) off your face. Aussie-born Ruggeri says a summer topper can also go so far as to protect your hair color investment, too. Moisture booster: There's nothing worse than realizing you've scored a red, painful sunburn after a day at the beach (Tsk-tsk, did you reapply your SPF?!—said in our most scolding, motherly-sounding voice). Regardless, when the day is over slather tender skin with Dermalogica After Sun Repair, a lotion that contains skin-soothing ingredients like cucumber, chamomile and hyaluronic acid.
